margin); each elytron with eight, at the extreme base with nine, rows of punctures, 
the second, fourth, and sixth interspaces, together with the suture, costate. 
In some specimens from Juquila the apices of the elytra are rather more strongly 
serrate.

Subelongata, fere parallela, nigra, eneo vix tincta, nitida; thorace elytrisque rufis, illo transverso, conico,. 
lateribus fere rectis, anguste nigris; dorso subcylindrico, disco pone medium paullo deplanato, crebre 
foveolato-punctato; elytris parallelis, sinuatis, apice obtuse rotundatis ; utrisque octo-, basi extrema nono- 
seriato-punctatis, interspatiis alternis costatis, costis duabus internis magis fortiter elevatis; plaga

Var, A. Elytrorum plaga discoidali obsoleta. 
Long. 33 lin. 
Hab. Mexico, Cordova (Hége). 
Head smooth; front moderately produced between the eyes, deeply trisulcate. 
Antenne robust, equal in length to the head and thorax; first and second joints short, 
the former slightly thickened, the third rather longer than the second, subovate, the’ 
fourth and fifth each equal in length to the second, the sixth very short, subturbinate, 
the seventh nearly twice its length ; club slightly compressed and dilated. Thorax about 
one fourth broader than long at the base; sides nearly straight, obsoletely bisinuate, 
obliquely converging from base to apex, the anterior angle armed laterally with a short 
acute tooth ; upper surface subcylindrical on the sides and at the apex, flattened on the 
hinder disc, closely and deeply foveolate-punctate. Elytra narrowly oblong, parallel, 
obtusely rounded at the apex, rather coarsely serrulate ; each elytron with eight, at the 
base with nine, regular rows of punctures; second and fourth interspaces rather 
strongly costate, the sixth less strongly elevated, finely serrulate below its middle. 
c. Elytra each with ten, at the extreme base with eleven, rows of punctures. 
o. Elytra rounded at the apex, emarginate at the sutural angle; apical margin spinous. . 
11. Uroplata bellicosa. 
Elongata, subparallela, nigra; subtus nitida, supra subopaca ; tarsis anticis capitisque maculis fulvis, femoribus 
anticis quatuor flavis; vertice utrinque fortiter sulcato; antennis rigidis, compressis, ad apicem attenu- 
atis; thorace conico, lateribus rectis, ad apicem sinuatis, angulo antico dente subacuto, obliquo armato, 
dense punctato, pone medium transversim excavato, utrinque vitta lata submarginali fulva; elytris ab 
ante medium apicem versus paullo ampliatis, apice rotundatis, ad suturam quadrato-emarginatis, irregula- 
riter spinosis; utrisque decem-, basi undecim-seriato-punctatis, interspatiis secundo, quarto octavoque, 
-* Since the Plate was drawn I have discovered that the specific name rubida under which I first described 
the above insect had been previously used for another species of the same genus. I have, therefore, been com- 
pelled to change it.
